Google Ads SERP Proxy

title: Google Ads SERP Proxy for competitive placement and creative capture

description: Build a Google Ads-focused residential proxy program that mirrors real user views by city and device, records exact ad positions, harvests display URLs and extensions, and exports audit-ready datasets for spend estimation, creative benchmarking, and bid intelligence—without triggering paid clicks or violating platform rules.

Search ads are hyper-contextual: who you are (device, locale), where you are (city, carrier), and when you search (daypart) all change which ads appear and in what order. A SERP proxy built for Google Ads prioritizes view fidelity over raw IP counts. Use geo-verified residential exits for discovery queries and rotate identities on natural boundaries (new query set, page depth, daypart), not on every HTTP request. Keep short-lived identities for broad sampling and sticky sessions for sequences that apply filters (language, location) so headers and cookies remain consistent.

• Geo calibration: route by city and align time zone and Accept-Language so local extensions (phone, address) render as a real user would see them.
• Device fidelity: maintain distinct desktop and mobile profiles—viewport, DPR, input type, and realistic network conditions—to surface mobile-only formats like image extensions and call buttons.
• Daypart sampling: schedule passes across business hours, evenings, and weekends to capture creative rotation and budget pacing effects.
• Ethical stance: never simulate paid clicks or conversions; capture what is already visible on the page and respect platform policies.

Raw HTML isn’t enough. Analysts need a clean record of which ad showed up where, for which query, and with what adornments. Your capture layer should materialize a structured SERP with stable keys and evidence where required.

• Position model: label each ad with slot metadata (absolute-top #1, top block rank, or bottom block) and scroll offset. Store the ad pack size and organic break position to measure “share above the fold.”
• Display URL & paths: parse the visible domain and path tokens separately (e.g., example.com + /pricing) to normalize brand vs. landing cues without following paid redirects.
• Extension coverage: extract sitelinks, callouts, structured snippets, promotion/price extensions, call extensions, image assets, and location overlays. Record per-extension presence plus the rendered copy.
• Creative fingerprint: normalize responsive search ad elements—headlines, descriptions, and assets—into a canonical set so A/B variants can be versioned over time.
• Evidence artifacts: optional 2× DPI PNGs of the ad block with a discreet watermark (query, locale, device, city, timestamp, hash) for audits.

Output as governed JSON so downstream teams can join by query, brand, and market without cleanup. Include provenance (request ID, city, ASN, user-agent profile) to make every row defensible.

Spend estimation. Build a position-weighted exposure index by query and market: more sightings at absolute-top count more than bottom-of-page. Combine exposure with public CPC ranges to approximate category spend and detect budget shifts (e.g., sudden drop in weekend top-slots).

Creative benchmarking. Track which headline themes (price-led, guarantee-led, social proof) correlate with persistent top positioning. Monitor extension mixes—how often rivals pair price extensions with promotions, or swap structured snippets for callouts—and summarize winning patterns by city and device.

Keyword & bid intelligence. Use ad density (ads per SERP), pack volatility, and competitor presence to flag expensive arenas and find underpriced long-tail. Detect brand bidding against your trademarks and map who appears when your organic rank dips. Feed insights to your bidding playbooks: protect brand at specific hours, push RSA assets that dominate mobile image extensions, or pause where exposure index collapses.

• Dashboards: exposure index by query, creative theme share, extension coverage heatmaps, and brand-term watchdogs.
• KPIs: absolute-top share, average ad rank proxy, extension presence rate, creative change velocity, and estimated spend index.

Choose partners on measurable fidelity, not promises about pool size. Run bake-offs with identical query lists and compare what truly matters for ads work.

• Geo precision: verifiable city-level routing with stable ASN diversity; consistent locale headers that match the route.
• Device emulation: accurate desktop/mobile profiles (viewport, DPR, input), HTTP/2/TLS fingerprints, and realistic network shaping for mobile tests.
• Render stability: high valid-SERP yield across dayparts; correct detection of “Sponsored” labels and ad pack boundaries; low variance in slot counts at depth.
• Data quality: JSON schemas with versioning; de-duplication by normalized creative + domain + query; evidence hashes for PNGs when used.
• Governance: explicit no-click policy for paid links, encryption in transit/at rest, minimal PII in logs, and retention controls.
• Commercials: pricing per 1k valid SERPs (not raw calls), with caps by market and device to prevent runaway budgets.

Call to action. If your team needs defendable views of who owns the top of the page—and why—pilot this SERP proxy in two markets for two weeks. We’ll wire dashboards for exposure, creatives, and extensions, and hand you a benchmark pack your CMOs and PPC leads can act on immediately.
